Unlike most theologians of his age, Martin Bucer proved to be farsighted with respect to European affairs: In addition to his contacts within Alsace and Germany he established relations with almost every European country. It was his ecumenical attitude that always led him to mediate between the parties in the religious battles of his time. His deep commitment to the goal of reaching agreement can be traced in all his activities, works and letters. Since the first editor, Jean Rott (Strasbourg), died in 1998, Bucer's correspondence has been edited in Erlangen. This academic edition of source material provides future research with a broad basis for significant aspects of Reformation history about which very little is known. Volume V covers the period from September 1530 to May 1531. It therefore mainly contains information about Bucer's diplomatic journey after the Augsburg Diet, his correspondence with the Valdesian synod of Merindol, his attempts to mediate between Luther and Zwingli with the help of his Konkordienschrift and to integrate the Swiss party in the Schmalcaldic confederation.
